<ol>
<li>实例化(Instantiation);</li>
<li>属性赋值(Populate);</li>
<li>初始化(Initialization);</li>
<li>销毁(Destruction);</li>
</ol>
<p><img src= "" data-lazy-src="https://gitee.com/xyingtao/blogimage/raw/master/img/640" alt="img"></p>
<ol>
<li><strong>实例化</strong>:第1步 实例化一个Bean对象</li>
<li><strong>属性赋值</strong>: 第2步 为bean设置相关属性的依赖</li>
<li><strong>初始化</strong>: 第3~7步,步骤较多,其中第5,6步为初始化操作,第3,4步为初始化之前执行,第7步在初始化后执行,该阶段初始化后执行,该阶段结束,才能被用户使用;</li>
<li><strong>销毁</strong>: 第8,9步,第8步不是真正意义上的销毁(还没使用呢),而是先在使用前注册了销毁的相关调用接口,为了后面第9,10步真正销毁bean时再执行相应的方法.</li>
</ol>
<p>下面结合代码来看,在doCreateBean()方法中可以看到一次执行了这四个阶段</p>

<p>由于初始化包含了3~7步,较复杂,所以我们进到initializwBean()方法里具体看下过</p>

<p>从 Spring 的源码我们可以直观的看到其执行过程，而我们记忆其过程便可以从这 4  个阶段出发，实例化、属性赋值、初始化、销毁。其中细节较多的便是初始化，涉及了  Aware、BeanPostProcessor、InitializingBean、init-method 的概念。这些都是 Spring  提供的扩展点，其具体作用将在下一节讲述。</p>
<h2 id="扩展点的作用"><a href="#扩展点的作用" class="headerlink" title="扩展点的作用"></a>扩展点的作用</h2><h3 id="Aware接口"><a href="#Aware接口" class="headerlink" title="Aware接口"></a>Aware接口</h3><p>若 Spring 检测到 bean 实现了 Aware 接口，则会为其注入相应的依赖。所以<strong>通过让bean 实现 Aware 接口，则能在 bean 中获得相应的 Spring 容器资源</strong>。</p>
<p>Spring 中提供的 Aware 接口有：</p>
<ol>
<li>BeanNameAware：注入当前 bean 对应 beanName；</li>
<li>BeanClassLoaderAware：注入加载当前 bean 的 ClassLoader；</li>
<li>BeanFactoryAware：注入 当前BeanFactory容器 的引用。</li>
</ol>
<p>其代码实现如下:</p>
<figure class="highlight java"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br><span class="line">3</span><br><span class="line">4</span><br><span class="line">5</span><br><span class="line">6</span><br><span class="line">7</span><br><span class="line">8</span><br><span class="line">9</span><br><span class="line">10</span><br><span class="line">11</span><br><span class="line">12</span><br><span class="line">13</span><br><span class="line">14</span><br></pre></td><td class="code"><pre><span class="line"><span class="comment">// AbstractAutowireCapableBeanFactory.java</span></span><br><span class="line"><span class="keyword">private</span> <span class="keyword">void</span> <span class="title function_">invokeAwareMethods</span><span class="params">(<span class="keyword">final</span> String beanName, <span class="keyword">final</span> Object bean)</span> &#123;</span><br><span class="line">    <span class="keyword">if</span> (bean <span class="keyword">instanceof</span> Aware) &#123;</span><br><span class="line">        <span class="keyword">if</span> (bean <span class="keyword">instanceof</span> BeanNameAware) &#123;</span><br><span class="line">            ((BeanNameAware) bean).setBeanName(beanName);</span><br><span class="line">        &#125;</span><br><span class="line">        <span class="keyword">if</span> (bean <span class="keyword">instanceof</span> BeanClassLoaderAware) &#123;</span><br><span class="line">            ((BeanClassLoaderAware) bean).setBeanClassLoader(bcl);</span><br><span class="line">        &#125;</span><br><span class="line">        <span class="keyword">if</span> (bean <span class="keyword">instanceof</span> BeanFactoryAware) &#123;</span><br><span class="line">            ((BeanFactoryAware)bean).setBeanFactory(AbstractAutowireCapableBeanFactory.<span class="built_in">this</span>);</span><br><span class="line">        &#125;</span><br><span class="line">    &#125;</span><br><span class="line">&#125;</span><br></pre></td></tr></table></figure>

<p>以上是针对 BeanFactory 类型的容器，而对于 ApplicationContext 类型的容器，也提供了 Aware 接口，只不过这些 Aware 接口的注入实现，是通过 BeanPostProcessor 的方式注入的，但其作用仍是注入依赖。</p>
<ol>
<li>EnvironmentAware：注入 Enviroment，一般用于获取配置属性；</li>
<li>EmbeddedValueResolverAware：注入 EmbeddedValueResolver（Spring EL解析器），一般用于参数解析；</li>
<li>ApplicationContextAware（ResourceLoader、ApplicationEventPublisherAware、MessageSourceAware）：注入 ApplicationContext 容器本身。</li>
</ol>
<p>其代码实现如下：</p>
<figure class="highlight java"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br><span class="line">3</span><br><span class="line">4</span><br><span class="line">5</span><br><span class="line">6</span><br><span class="line">7</span><br></pre></td><td class="code"><pre><span class="line"><span class="comment">// ApplicationContextAwareProcessor.javaprivate void invokeAwareInterfaces(Object bean) &#123;    if (bean instanceof EnvironmentAware) &#123;        ((EnvironmentAware)bean).setEnvironment(this.applicationContext.getEnvironment());    &#125;</span></span><br><span class="line">    <span class="keyword">if</span> (bean <span class="keyword">instanceof</span> EmbeddedValueResolverAware) &#123;        ((EmbeddedValueResolverAware)bean).setEmbeddedValueResolver(<span class="built_in">this</span>.embeddedValueResolver);    &#125;</span><br><span class="line">    <span class="keyword">if</span> (bean <span class="keyword">instanceof</span> ResourceLoaderAware) &#123;        ((ResourceLoaderAware)bean).setResourceLoader(<span class="built_in">this</span>.applicationContext);    &#125;</span><br><span class="line">    <span class="keyword">if</span> (bean <span class="keyword">instanceof</span> ApplicationEventPublisherAware) &#123;        ((ApplicationEventPublisherAware)bean).setApplicationEventPublisher(<span class="built_in">this</span>.applicationContext);    &#125;</span><br><span class="line">    <span class="keyword">if</span> (bean <span class="keyword">instanceof</span> MessageSourceAware) &#123;        ((MessageSourceAware)bean).setMessageSource(<span class="built_in">this</span>.applicationContext);    &#125;</span><br><span class="line">    <span class="keyword">if</span> (bean <span class="keyword">instanceof</span> ApplicationContextAware) &#123;        ((ApplicationContextAware)bean).setApplicationContext(<span class="built_in">this</span>.applicationContext);    &#125;</span><br><span class="line">&#125;</span><br></pre></td></tr></table></figure>

<h3 id="BeanPostProcessor"><a href="#BeanPostProcessor" class="headerlink" title="BeanPostProcessor"></a>BeanPostProcessor</h3><p>BeanPostProcessor 是 Spring 为*修改 bean *提供的强大扩展点，其可作用于容器中所有 bean，其定义如下：</p>
<figure class="highlight java"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br><span class="line">3</span><br><span class="line">4</span><br></pre></td><td class="code"><pre><span class="line"><span class="keyword">public</span> <span class="keyword">interface</span> <span class="title class_">BeanPostProcessor</span> &#123;</span><br><span class="line">    <span class="comment">// 初始化前置处理    default Object postProcessBeforeInitialization(Object bean, String beanName) throws BeansException &#123;        return bean;    &#125;</span></span><br><span class="line">    <span class="comment">// 初始化后置处理    default Object postProcessAfterInitialization(Object bean, String beanName) throws BeansException &#123;        return bean;    &#125;</span></span><br><span class="line">&#125;</span><br></pre></td></tr></table></figure>

<p>常用场景有：</p>
<ol>
<li>对于标记接口的实现类，进行自定义处理。例如3.1节中所说的ApplicationContextAwareProcessor，为其注入相应依赖；再举个例子，自定义对实现解密接口的类，将对其属性进行解密处理；</li>
<li>为当前对象提供代理实现。例如 Spring AOP 功能，生成对象的代理类，然后返回。</li>
</ol>
<figure class="highlight plaintext"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br></pre></td><td class="code"><pre><span class="line">// AbstractAutoProxyCreator.javapublic Object postProcessBeforeInstantiation(Class&lt;?&gt; beanClass, String beanName) &#123;    TargetSource targetSource = getCustomTargetSource(beanClass, beanName);    if (targetSource != null) &#123;        if (StringUtils.hasLength(beanName)) &#123;            this.targetSourcedBeans.add(beanName);        &#125;        Object[] specificInterceptors = getAdvicesAndAdvisorsForBean(beanClass, beanName, targetSource);        Object proxy = createProxy(beanClass, beanName, specificInterceptors, targetSource);        this.proxyTypes.put(cacheKey, proxy.getClass());        // 返回代理类        return proxy;    &#125;</span><br><span class="line">    return null;&#125;</span><br></pre></td></tr></table></figure>

<h3 id="InitializingBean-和-init-method"><a href="#InitializingBean-和-init-method" class="headerlink" title="InitializingBean 和 init-method"></a>InitializingBean 和 init-method</h3><p>InitializingBean 和 init-method 是 Spring 为 <strong>bean 初始化</strong>提供的扩展点。</p>
<p>InitializingBean接口 的定义如下：</p>

<p>在 afterPropertiesSet() 方法写初始化逻辑。</p>
<p>指定 init-method 方法，指定初始化方法：</p>

<p>DisposableBean 和 destory-method 与上述类似，就不描述了。</p>
<h2 id="总结"><a href="#总结" class="headerlink" title="总结"></a>总结</h2><p>最后总结下如何记忆 Spring Bean 的生命周期：</p>
<ul>
<li>首先是实例化、属性赋值、初始化、销毁这 4 个大阶段；</li>
<li>再是初始化的具体操作，有 Aware 接口的依赖注入、BeanPostProcessor 在初始化前后的处理以及 InitializingBean 和 init-method 的初始化操作；</li>
<li>销毁的具体操作，有注册相关销毁回调接口，最后通过DisposableBean 和 destory-method 进行销毁。</li>
</ul>
